7 Claims.

This invention relates to adjustable collapsible forms used in concreteconstruction, and in particular collapsible forms that are readily setup and taken down after use and that are readily adjustable to formwalls, oors, and the like in buildings of diierent dimensions.

The purpose of this invention is to provide means in a form,channel-shaped in cross section whereby mounting members extended fromthe ends of units of the form are adjustably mounted in thechannel-shaped units.

Various'types of connections have been pro vided in the ends of wall andloor forms for use in concrete construction but where the ends of theforms are adjustably connected it is difcult to frame connectingelements into spaces at the ends of the forms and at the same timeprovide a smooth wall surface all of the way to the connecting wall orjoint. With this thought in mind this invention contemplates formingwalls and deck or floor forms, channel-shaped in cross section andproviding telescoping or Slidably mounted tongues in the ends of thesections whereby the tongues are extended to correspond with the lengthor width of a oor or wall and secured in position by nails extendedthrough openings in the forms and wood strips in the tongues and inwhich the areas between the ends of the sections and ends of the tonguesare filled in with wood strips to provide a continuous wall surface.

The object of this invention is, therefore, to provide collapsible formsfor concrete construction in which tongues are adjustably mounted in theends of units of the forms for extending the length thereof.

Another object of the invention is to provide means for forming wallforms with tongues adjustably mounted in the ends of sections thereof inwhich the tongues are held by nails to facilitate setting up and takingdown the forms.

A further object of the invention is to provide adjustable elements inthe ends of units of deck and wall forms in which the forms are ofsimple and economical construction.

' With these and other objects and advantages in View the inventionembodies deck and wall forms provided in units with each unit includingafacing plate reinforced at the center and also at the edges withstructural shapes, with spaced box-like members positioned in the endsand with tongues having wood strips therein adjustably mounted betweenthe said box-like members.

. -Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings wherein:

Figure 14 is a longitudinal section taken on line I 4-I4 of Figure 13showing the construction of the U-shape channels in the ends of theform.

Figure l5 is a cross section through an end of one of the forms, takenon line l5-I5 of Figure 13 illustrating the structure at the ends and inone side of the forms and showing the nails extended into wooden stripsin the tongues adjustably mounted in the form.
